Stewart graduated from the University of Lancaster in Politics and Marketing. In 1975 Stewart pioneered a research project on Open Government at the UK Consumers’ Association. He then visited the USA and Canada, meeting consumer advocates, politicians and journalists researching the emerging Freedom of Information and privacy legislation. His subsequent publication was financed by the Outer Circle Policy Unit, titled Open Government: Lessons from America, and a new career was born. Consumer research and working for The Economist as a business journalist honed his skills as an investigator and writer.
He launched the Privacy Laws & Business Newsletter in February 1987. In October 1988 he organised PL&B’s first international conference. Stewart co-founded and chaired the UK’s Data Protection Forum, and has spoken at conferences around the world. He lives and works in Pinner, has a beautiful wife, who wrote this, and 3 adult sons.
